Description

FIELD OF THE INVENTION

The present inventions relate to gas grills. More particularly, the present inventions relate to mounting brackets that secure the gas distribution manifold to both the fire box and grill frame.

BACKGROUND OF THE INVENTION

Many available gas grills typically include a support frame or cart, often with wheels and shelves for accessories and the like. They also include a cooking chamber or fire box having a hinged lid. The fire box accommodates the gas distribution components, such as the burner tubes, cooking grates and the like. Other gas distribution components, such as the valves and manifold, are typically attached to the burner tubes. The fire box is attached to and sits on the support frame.
Many gas grills are sold in a partially disassembled state for ease of shipping and are to be assembled by the consumer. Typically, the fire box, including the gas distribution components, is packaged and shipped as one complete subassembly. This is done for safety reasons and particularly, so that the consumer is only required to make a minimum of gas supply and/or distribution connections. The support frame, on the other hand, typically requires more assembly by the consumer. Once the support frame is assembled, the fire box and its gas distribution components are placed on the frame and attached thereto.
In typical gas grills, a gas distribution manifold, which is the component that distributes the gas through the valves and to the burners, is typically supported by one or more brackets that mount the manifold (which in turn helps support the valves and burner tubes) only to the fire box. While this arrangement is adequate for many situations, more stability and support for the gas manifold and associated components may be desirable.
Therefore, it is an object of the present inventions to stabilize the gas distribution manifold when the gas grill is assembled, while still permitting ease of assembly by the consumer without the need for specialized tools.
It is an additional object of the present inventions to simultaneously mount the gas distribution manifold to the fire box and the grill support frame.
It is a further object of the present invention to produce gas distribution manifold mounting brackets that secure the gas distribution manifold to the grill frame and the fire box for additional security and stability.

NOTICE OF CLAIM OF COPYRIGHT PROTECTION

A portion of the disclosure and drawings of this patent document contains material which is subject to copyright protection. The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the U.S. Patent and Trademark Office files or records, but otherwise reserves all rights.
United States patent specification no. US 2008/216813 discloses an improved baffle plate structure of a far-infrared core of the griller. The baffle plate is horizontally mounted at regular intervals over the far-infrared core of the existing griller. The baffle plate has a predefined profile, thickness and light transmission property. The baffle plate has a facade in a curved shape forming at least a convex portion and two falling sides. The convex portion faces upwards, and two falling sides of the baffle plate are extended to two predefined positions at both sides of the far-infrared core, thus enabling the baffle plate to cover the top surface of far-infrared core. The convex portion of the curved baffle plate allows oil stains or other foreign materials to be discharged towards two falling sides, thus avoiding the accumulation of foreign materials.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Set forth below is a description of what is currently believed to be the preferred embodiments or best representative examples of the inventions claimed. Future and present alternatives and modifications to the embodiments and preferred embodiments are contemplated. Any alternatives or modifications which make insubstantial changes in function, purpose, structure or result are intended to be covered by the claims of this patent.
A representative gas grill to which the present inventions may apply is shown generally as 10 in Figure 1. It includes a support frame assembly 12 and a fire box or cooking chamber 14 having a hinged lid (not shown). A control panel 16 and knobs 17 to operate the gas valves 33 (not shown in Figure 1) are also provided. The fire box 14 is supported by and attached to frame 12 in a manner that is understood by those of ordinary skill in the art.
The typical gas supply and distribution assembly 30 and fire box 14 are shown in Figures 2-4. The fire box 14 includes two side walls 20, a back wall 21 and a front wall 22. Fire box 14 also includes a ledge 23 to accommodate sear bars (not shown) or other similar components. Fire box 14 also includes a lip 24, typically on the front 21 and back 22 walls to accommodate and support a cooking grate (not shown) or similar surface.
A typical gas supply and distribution assembly 30 includes burner tubes 31, a cross pilot tube 32 and gas valves 33. As shown in Figures 2 and 4, the burner tubes 31 are attached at one end to the rear wall 21 of fire box 14. The other end of burner tubes 31 protrude through holes 25 provided in the front wall 22 of fire box 14. Valves 33 are affixed to the ends of the burner tubes 31. Valves 33 are in turn attached to and in fluid communication with the gas distribution manifold 35. The gas distribution manifold 35, and components attached thereto, are supported by a gas manifold mounting bracket 40 of the present inventions as hereinafter described. A gas supply line 36 is also provided which is in fluid communication with the gas distribution manifold 35.
As will be understood by those of ordinary skill in the art, gas supply line 36 is ultimately connected to a gas source (not shown), such as a tank or gas line. In operation, gas flows from the gas source through the gas supply line 36 and into gas distribution manifold 35. As its name connotes, gas distribution manifold 35 distributes the gas through the selected valves 33 and to the burner tubes 31 where the gas is ignited and ultimately used for cooking.
The gas supply and distribution assembly 30, and particularly the gas distribution manifold 35, is supported by gas manifold mounting bracket 40. As shown in Figure 2, a first end or manifold support portion 41 of mounting bracket 40 supports gas distribution manifold 35. A back end or fire box attachment portion 42 of mounting bracket 40 is adapted to be attached to the front wall 22 of fire box 14. In a preferred embodiment, tabs 44 are formed into back end 42 or fire box connection point and are secured to the fire box 14 by a nut and bolt. Those of ordinary skill will understand that the bracket 40 may take a variety of forms and be attached to the fire box 14 and gas distribution manifold 35 in a variety of ways consistent with the present inventions. It will also be understood that mounting bracket 40 may be made from a variety of materials consistent with its environment of use and safety and regulatory considerations.
Importantly, manifold bracket 40 is also adapted to provide a portion that may be secured to the grill frame assembly 12. As best shown in Figures 2 and 3, an intermediate or frame connection portion 43 of mounting bracket 40 is provided with a tab or similar means that is secured to the grill frame assembly by a nut and bolt or other well known means. It will be understood that the intermediate portion 43 may also take a variety of forms consistent with the present inventions. In this manner, the manifold mounting bracket 40 provides extra support and security by mounting the gas distribution manifold 35 simultaneously to both the fire box 14 and frame 12.
When a typical grill assembly is shipped in the usual partially assembled form, the fire box will preferably include the components shown in Figure 4 pre-assembled. Specifically, the burner tubes 31, cross pilot tube 32, valves 33 and gas distribution manifold 35 supported by manifold mounting bracket 40 are preferably attached at the factory. As shown, gas manifold mounting bracket 40 is secured to fire box 14, but is not secured to frame assembly 12 when shipped. When the consumer assembles the support frame 12, they attach the fire box 14 (for example, as shown in Figure 4) to the support frame 12. The consumer will then secure gas mounting manifold bracket 40 to the grill support frame as shown in Figures 2 and 3. It will be understood, however, that the foregoing is a desired application of the present inventions, but is not required.
The above description is not intended to limit the meaning of the words used in or the scope of the following claims that define the invention. Rather, it is contemplated that future modifications in structure, function or result will exist that are not substantial changes and that all such insubstantial changes in what is claimed are intended to be covered by the claims. Thus, while preferred embodiments of the present inventions have been illustrated and described, it will be understood that changes and modifications can be made without departing from the claimed invention. In addition, although the term "claimed invention" or "present invention" is sometimes used herein in the singular, it will be understood that there are a plurality of inventions as described and claimed.
Various features of the present inventions are set forth in the following claims.
